Moreover, as a construction product manufacturer, ArcelorMittal Europe proposes an extended range of profiles and sandwich panels for roofing solutions, as listed below:

Sandwich panels made of steel have become one of the most recognized solutions for insulated buildings. ArcelorMittal sandwich panels for roofs have a PUR / PIR or mineral wool insulation core and thus have an insulating, fire-resistant and flame retardant function. The roof panels are suitable for areas with low or medium high humidity. Sandwich panels are widely used for finishing off shed, barn and hall roofs, or food industry buildings with low or even negative temperature.

ArcelorMittal also produces Eco roof panels, which, among others, are very suitable for agricultural buildings.

Innovative Komet® profiles have been developed to ensure quick erection methods for solar panels on roofs and optimized solar cells efficiency.

By choosing ArcelorMittal’s best in class products, you can extend the lifetime of the roofing system beyond 40 years. Working with us, you receive a guaranteed quality and sustainability, as our products are certified as free of chromates and heavy metals (compliant with European REACh regulation and ECCA Premium label).

Roofing

Steel roofing solutions are growing in popularity as architects, designers and homeowners seek out stylish, modern alternatives to traditional materials. More and more architects are considering roofing as the “fifth façade” of buildings. Metallic roofing offers endless possibilities not only to express creativity, but also to make manufacture affordable.

However, steel roofs are popular due to more than just visually pleasing aesthetics. They are also extremely lightweight, cost-effective, quick and easy to install, and can increase the value of your building as a result of their low maintenance and durability. In addition, they largely contribute to thermal and energy building efficiency.

ArcelorMittal Europe offers steel products and solutions that can adapt to most roofing and guttering applications, including:

Full range of Metallic coated and Organic coated steels for any kind of roofing solution.

Tile or slate patterns with Granite® Impression Cloudy and Granite® Storm. Roofing tiles made of steel combine a wide range of aesthetics with all the advantages of metal: lightness, possibility of low slope, ease and speed of installation, resistance to climate and watertightness.

Standing seam roofs with Aluzinc® HFX and Granite® HFX Cool. Standing seams have been used for hundreds of years to seal metal roofs. Typically found in cold climates, the standing seams keep the vulnerable connections above the snow level, ensuring they remain dry. Standing seams also provide additional visual interest – whether they are oriented vertically, horizontally or at an angle. They also enables complex curved and long span roofing solutions. There are different types of standing seam roofing systems available on the market. The first type is made of profiled sheets, which are then assembled on the roof. For the second type, the metal is delivered in sheets or small coils, which are seamed directly on the roof by the installer.

Since the early 2000s, Grand Line has been working with organic coated steels from ArcelorMittal Europe – Flat Products for its range of roofing tiles and accessories. The products are used by Grand Line’s customers for the roofs of cottages and low-rise constructions. Today Grand Line is utilising ArcelorMittal’s Granite® HDX for its Quarzit range because it offers excellent performance in the harsh Russian climate.

Grand Line began buying Granite® HDX when its customers started demanding a high-performance roofing solution with a polyurethane coating. “At the time, another steelmaker was offering this solution so our customers were naturally interested,” explains Sergey Namestnikov, head of marketing. “We searched for a product that would offer the same outstanding colour and gloss retention and found Granite® HDX from ArcelorMittal for our Quarzit range.”

Colour selection suits local aesthetics

Granite® HDX is available in a wide range of colours and metallic shades, however, Grand Line uses a limited selection, notes Sergey Namestnikov: “From the Granite® HDX colour palette we mainly choose dark colours such as moss green, copper brown and chocolate brown, which ArcelorMittal colour-matches for us to ensure consistency. On top of this standard offer, we ask for special colours including copper which suit the aesthetics of our local market.”

In addition to roofing solutions, Grand Line creates metallic siding and corrugated profiles. “Many of these products are created with Access Standard and other steels from ArcelorMittal’s Granite® range including Standard, HD, Storm, and Deep Mat,” says Sergey Namestnikov. “And we make gutters out of Granite® Rain HDS.

Innovation days facilitate knowledge exchange

Grand Line has a stand where ArcelorMittal materials are tested in natural conditions to ensure their suitability for the Russian climate, notes Sergey Namestnikov: “This allows us to have a continuous exchange with ArcelorMittal about the corrosion tests, and to provide them with feedback from the end users of our products. Since 2014, we have held innovation days at least once a year to facilitate the feedback process. We are in contact with ArcelorMittal’s technical support teams on a regular basis for any immediate questions or issues.”

Grand Line

Founded in 1965, Grand Line has grown to become one of the largest producers of building materials for cottages and low-rise construction in Russia. The company employs more than 3,000 people at its seven plants in Russia. Grand Line’s Vorsino plant is one of the most advanced in Russia and utilises a range of technologies not found elsewhere in the country. Grand Line exports to every region of the country as well as to Belorussia, Kazakhstan, and Latvia.

Bacacier is one of France’s leading manufacturers of steel roofing and cladding solutions for the building and construction sector. With an eye on constant innovation, Bacacier is always looking for new aesthetic steel solutions to enhance its range of products. Thanks to a close relationship with ArcelorMittal Europe – Flat Products, Bacacier was a key partner in the development of Granite® Quartz in France and is now incorporating it into their latest products.

Bacacier is constantly innovating its product range to bring the best steel solutions to its customers. Unlike many of its competitors, Bacacier creates products for both professionals and the fast-growing do-it-yourself (DIY) market.

A durable and attractive solution

Bacacier has recently created a new range of construction materials using Granite® Quartz from ArcelorMittal. “We are always looking for new finishes and Granite® Quartz was a good solution thanks to its look and feel, and scratch resistance,” explains Luc De Deygere, purchasing director of Bacacier. “Scratch resistance is very important – particularly for our roofing solutions.”

Bacacier was closely involved in industrial-scale trials of Granite® Quartz notes Luc De Deygere: “ArcelorMittal does not just sell us coils. We sit with their technical people and explain our needs. Together we can co-engineer products for the future. When ArcelorMittal first proposed the idea of Granite® Quartz, we immediately saw the potential of this durable and attractive solution.”

Although Bacacier has only recently introduced Granite® Quartz to its professional clients, sales are steady says Luc De Deygere: “It’s only been on the French market for a few months, so customers are still becoming aware of Granite® Quartz. But their initial reactions have been overwhelmingly positive. We see a bright future for Granite® Quartz as part of our portfolio.”

Bacacier’s Tuile R PRO system simplifies the construction process and comes with a 20-year guarantee.

ArcelorMittal's prepainted steel Granite® Impression - Brown Agate was chosen as the material for the new roof of a fieldstone church in Poland: Its authentic look and excellent resistance provide the perfect combination for the necessary aesthetic and functional requirements of this roof renovation project.

Due to its advanced state of deterioration, the roof of the catholic St. Bartholomew church in the Polish town of Troszyn was replaced by a steel roof, using roofing profiles made of prepainted steel produced by ArcelorMittal Europe - Flat Products.

The local Polish company Kurp-dach, a fabricator of steel roofs and long-time ArcelorMittal customer, chose ArcelorMittal's prepainted steel Granite® Impression - Brown Agate for this project as it fulfilled the aesthetical as well as functional requirements and constitutes a very cost-efficient alternative in comparison to e.g. clay tiles or copper.

With it's brownish-red shade, Granite® Impression in its variation Brown Agate features polished patterns with the impression of iron oxide inlays and imitates the surface of copper, but at a lower cost.

The Granite® Impression product line is unique in its aesthetical characteristics on the European market.

For the renovation of this church roof, ArcelorMittal supplied to Kurp-dach a total of 15,6 tonnes of Granite® Impression- Brown Agate prepainted steel, with two different metallic substrates and dimensions: 11,6 tn of S250 Z275 in coils of 0,6 x 1250 mm and 4 tn of S320 Z275 0,7 x 1222 mm.

Granite® Impression Cloudy gives panamanian homes the vintage look

For home owners in Latin America, the traditional look of roofing tiles is becoming more and more important. As a cost efficient alternative to clay tiles, metal tiles with Granite® Impression Cloudy coating is becoming increasingly popular as its cloudy effect gives roofs the vintage look the customer is looking for and stands for quality made in Europe.

When it comes to choosing a roofing solution for their new home, many Latin American buyers opt for clay tiles to recreate the look of traditional housing. In Panama, customers often seek out second-hand clay tiles which are at least 10 years old. These older terracotta tiles develop a patina which gives them a mottled black-brown colour. It can make a new home look as though it has been around for decades.

Thanks to Formetal, Panamanian home owners no longer have to seek out these expensive and heavy clay tiles to give their home the instantly aged look. Formetal has joined a growing number of companies in Latin America which are offering ArcelorMittal’s Granite® Impression Cloudy as roofing tiles, and it’s proving to be a very popular solution.

“Granite® Impression Cloudy represents an evolution in our line of metal tiles,” notes Esteban Lam, general manager of Formetal. “Our customers like the cloudy effect as it gives them the vintage look they want for their house.”

Made in Europe

Formetal has worked with ArcelorMittal since 2011. The company utilises ArcelorMittal pre-painted coils such as Granite® Standard and Granite® HD for profiles, and galvanised steels for their heating, ventilation and air conditioning (HVAC) products.

Granite® Standard and Granite® HD were also applied to Formetal’s roofing solutions, offering customers a large range of colours. “We upgraded some of our products in 2014 and decided to enhance our offer with Granite® Impression Cloudy,” notes Esteban. “Thanks to its 35 micron coating, it offers better UV resistance and a lower gloss level than the other products we have tried. Granite® Impression Cloudy also has the antique patina our customers love.”

A key consideration for tile customers is the fact that Granite® Impression Cloudy is made in France says Esteban: “During our sales pitch we stress that Granite® Impression Cloudy is manufactured in Europe, not in Asia. It’s a major selling point for our customers.”
